In Winnipeg it might be different, but it is almost exclusively scouting staff across the league as
@axecrew can attest to.
There are other teams without their AHL team in their backyard. Edmonton, St. Louis, Carolina, Milwaukee, Seattle... so it certainly isn't only the Southern teams.
Your point on the supposed flex schedule functionality also doesn't hold up to scrutiny as axecrew also points out.
Charlotte is still an outlier with both of Florida's teams in Jacksonville/Orlando/Estero. They require a flight or a long bus trip. So now you have multiple teams on an island instead of just Charlotte. So that doesn't hold up to closer scrutiny.
You talk of mitigating operating costs... requiring a flight or an insanely long bus trip for *every single away game* balloons costs far more than whatever you would get in increased ticket revenue.
Let's go down the rabbit hole and say let's say you move Syracuse to Jacksonville. You're making the assumption Jacksonville is going to maintain their attendance at 8500/game. You really think people in Jacksonville want to watch hockey in the same numbers with increased ticket prices from going up to the AHL, when the closest team is Charlotte and then after that it's Hershey? Even if you had Orlando, adding one team doesn't change my point. They are regularly playing teams nowhere near them and ones no one cares about. Their current
longest ECHL divisional matchup is comparable to their second
closest AHL opponent and that's
if you move Florida and Tampa's affiliate closer. Attendance won't hold steady, even if they're affiliated with a nearby team. Fans don't care about how close their affiliate is. Coachella Valley, Springfield, there are plenty of other examples of there being no correlation between geographic proximity to NHL affiliate and increased attendance.
And let's say hypothetically it does hold steady. If so, 8500 per night. Coach buses are roughly $2000 per day if you want to do all bus trips, which you won't with your third closest team
in the best case scenario being in Hershey. Chartered jets for pro hockey teams nowadays start at $7500 per hour. So 8500 in attendance, something way higher than you would even be able to draw, wouldn't be enough to offset your travel costs.
"Growing the game" means getting butts in seats, increasing interest in hockey, and getting more kids playing. That is sometimes inherently incongruent with swapping leagues where it doesn't make sense. It is completely incongruent in this case.
It makes perfect sense because of this: it is a development league. The whole point of the AHL is to develop prospects. Nothing more. And to do that, you need to minimize travel because there is beyond enough definitive evidence to show players do better when they spend less time on the road and more time in the gym, on the ice, and sleeping in their own beds.
